This is my first post. I am at the beginning of a build and just mounted the wings on the fuse. I've got kitfox wings with the old spar where you don't have to insert the I-Beam. I understand that scuffing the spar with 220 grit is acceptable according to the manual. However, underneath the strut brace, the spar was prepped with something closer to 80 grit. Since the strut brace is riveted and hysoled to the spar, this is like a "doubler" or reinforcement. Of course, I am not sure.
I believe I have to start over which sucks greatly, but was wanting some concurrence.
Pictures show the scratches-(no other parts of the spar are scratched as such).
Thanks and look forward to your responses and expertise-
